' IMPROVED NAILING- on PEG-GING-MACHINE.

The Schedule referred to in these Letters Patent and making P 1: 0! thesame.

county of Suffolk, and State of Massachusetts, have invented anImprovement in Nailing or Pegging-Ma- I chines; and I do hereby declarethat the following,

taken in connection with the drawings which accompany and form part ofthis specification, is a description of my invention sufficient toenable those skilled in the art to practise it.

I In that class of machines designed for making use of wire-likematerial, from which short lengths are cut, and driven into the soles ofboots and shoes, to secure them to their vamps, it is a desideratnm tocut, before driving, each fastening, from the wire-like material, of alength proportioned to thethickness of the material where the fasteningisinserterh-in order to prevent waste of the pegging ornailing-materiahto save labor in getting rid of inwardly-projecting peg or nail-ends,and to leave the inner surface of thecinner sole smooth and tree fromprojections. a

I accomplish this by making use of what is well known, in sole-sewingmachines, as a horn, modifying it so that its salient end issolid, likean anvil-face, and arranging the horn so that it can move toward andfrom the presser-foonor the end of the nail or pegtube of a pegging ornailing-mechanism, and so that the thickness of the sole of aboot orshoeis calipered between the horn-end and the end of the peg or nailtubeor the presser-foot, thehorn receiving and resisting the blows orthrusts necessary for the insertion of the pegs or nails, and being soarranged and connected with the mechanism whichfeeds the wire-likepegging or nailing-material, as to vary the successive feedingmovementsof the wire, and cause them to supply to the cutting anddriving-mechanism lengths corresponding to the varying thickness of thesole at the parts that are brought successively over the end of thehorn, which is inserted in the boot or shoe, with, its anvil-facebearing against the inner surface of the inner sole.

In the drawings--- Figurelshows, inside elevation, a machine embodyingmy invention;

Figure 2 being a front elevation of the machine; and

Figure 3 being a partial rear elevation of the same.

a represents the standard of a nailing or peggingmachine, adapted to cutfrom wire-like material, pieces attached, a born, 0, so that the hornend can be moved" toward and from the end of the peg or nail-tuhe, orthe presses-foot d. I

The horn is fixedon the shaft c, which is guided in bearings ff, fixedto the standard a, the lower end of the horn-shaft being stepped in agroove in the weighted lever b.

In the head g, of the pcgging or nailing-machine, are joinnalled twoparallel shafts, on which are fixed two grooved wheels, h i, so thatwhen the wire-like material, which is preferably supplied from a reelattached to the machine, is introduced into the bite of the groovedwheels, it will be fed down to the cutters when motion is given to thewheels h 'i, or either of them, in the proper direction.

On the other end of the shaft of Wheel h is pivoted an arm, j, one endof which is vibrated at the proper times and to the necessary extent, byconnection with the shaft, which works the pegging or nailing-mechanism,which is not shown, as it constitutes no part of my present invention.

To the other end of arm j is pivoted a pawl, 70, which meshes into andturns a ratchet-wheel, l, fixed on the shaft of the wheelie There isalso pivoted on said shafii, a shield, m, which projects over part ofthe ratchet-wheel teeth, so that if any part of the projection comesbeneath the end of the pawl, in its stroke, the action of the pawl onthe ratchet-whcel is diminished The shield on has an arm, by which,through the link a, it is connected to the weighted lever b, so that theposition of the part of the shield which projects over theratchet-teeth, with reference to the pawl, is dependent upon theposition of the born with reference to the tube or presser-d.

To adjust the parts thus ,working in combination, the link it is madeadjustable in length, and is also made adjustable as to the distance ofits connection from the axis about which the shield turns.

- It will be seen that as the horn-end approaches the end of tube orpresser (I, the shield is advanced under the pawl, thus lessening thelength of the wire fed to the sole, and, as the horn-end is removed.from the creasing the feeding-movement of the wheel h, and the length ofthe wire supplied to the sole;

By suitable adjustments, by the means described, the feed of the wn'en'ke material can'be made equal or slightly in excess or in diminutionof such distances. I claim the combination of the vertically-moving bornwith the feeding-mechanism of the wire-like material, so that the feedof said material shall be in pro portion to the thickness of the stockat the points at which fastenings are to be inserted, substantially asdescribed.
